Fig. 3From: Inactivation of mammalian spermatozoa on the exposure of TiO2 nanorods deposited with noble metalsComparison of total motile sperm and progressive motile sperm after incubation with or without (W/O) TiO2 NRs. Boar spermatozoa were incubated in the presence of TiO2 NRs for 10 min (A, B) and 2 h (C, D). Values are expressed as mean ± SEM. Lines (or dotted lines) among columns denote significant differences at *p < 0.05, **p < 0.01 and ***p < 0.001Back to article page
